Virtually all page layout, word-processing, and graphic applications accept imported or placed encapsulated PostScript (EPS) files. The EPS format preserves many of the graphic elements you can create with Adobe Illustrator, which means that EPS files can be reopened and edited as Illustrator files. Because EPS files are based on the PostScript language, they can contain both vector and bitmap graphics.
If you select TIFF (8‑bit Color) format, select a background option for the preview image:
If you choose a CS format, specify how to save overlapping colors that are set to overprint, and select a preset (or set of options) for flattening transparency. Click Custom to customize the flattener settings.
If you choose a Legacy format earlier than 8.0, select Preserve Paths to discard transparency effects and reset transparent artwork to 100% opacity and Normal blending mode. Select Preserve Appearance and Overprints to preserve overprints that don’t interact with transparent objects. Overprints that interact with transparent objects are flattened.
